Validate VAT numbers in Exact Online
The connector automatically validates the VAT number and address details of your foreign customers. We inform you about incorrect VAT numbers so you can be sure whether that customer is a business owner. This helps you prevent possible retrospective tax assessments because VAT was unjustly not paid on your supplied goods and services.

Automatic VAT Number Check

Certainty that it concerns business deliveries
When you provide goods or services to a client, it is important to know whether that client is indeed a business operator. You will receive a retrospective tax assessment if it turns out during the administration check that your client is not a business operator. In other words, VAT must then still be paid on the goods and services you provided.

Quick Validation of VAT Numbers
To ensure you are dealing with a business, it is useful if you can check their VAT identification number. This can be done on the website of the Tax Service, but it is not practical if you must manually enter a number every time. The connector does this fully automatically for you.

Different control moments for certainty.
Our VAT number validator operates at five different times. First, the app performs a one-time overall check after the first installation. Furthermore, the validator checks the data when you create a new CRM relationship, modify a CRM relationship, or record a new transaction connected to a CRM relationship.
